Ronald E. Nelson: trading record in brief

All filings by Ronald E. Nelson on record concern Columbia Sportswear Co, in the capacity of senior executive. Over a trading history stretching from 25 May 2016 to 27 May 2026, the count stands at 36 filings.

No open-market purchase appears, only 4 sales worth €1.0M. The rest of the record consists of 32 option exercises. In 2026 alone, the filings show no purchases and 1 sale.

The record was last updated on 29 May 2026 with an option exercise (€159k) in Columbia Sportswear Co. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. The legal deadline for a Form 4 is two business days after the transaction. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify.
